shop: revert product card tone back to cream

The brand-green media wash was only meant for the homepage's
3-product teaser, not the full shop catalogue. Reverts ShopPage's
ProductCard tone from `brand` → `cream` so shop cards keep the
cream image area / paper body that the rest of the catalogue uses.
